Issues with Cisco Firepower eStreamer service (Splunk Add-On)

[balbano_cfg]

Hi,

We are running into an issue where the Splunk eStreamer Technical Add-On keeps crashing when receiving events from our Cisco Firepower instance.

The exact error logs being observed on the Splunk side are as follows:

2021-12-17 09:19:23,377 root INFO 'latin-1' codec can't encode character '\u2013' in position 460: ordinal not in range(256)

2021-12-17 09:19:23,385 Writer INFO Error state. Clearing queue

We have also updated the TA to the latest version (4.8.3) as noted on the Splunk Add-On page for the app: https://splunkbase.splunk.com/app/3662/

On the HF side, we also increased number of worker processes from 4 to 8 which did not help. 

Wondering if anyone experienced the same issues. 

Let me know. 

Thanks.
